Soil 101

Have you ever wondered why most soils are lacking the nutrients or soil structure needed to support healthy plant development?

The truth is the nutrients that plants require are contained in dirt. The trick is turning dirt into soil requires life in the soil. 

Life requires food.

Explanation of Soil Food Web

Bacteria break down minerals contained in rock, silk, sand, and clay through alkaline enzymes to consume the nutrition they need.

Meanwhile, fungi use acidic enzymes to break down organic matter.

Step 03

Enzymes are the same thing we use when we breathe on glasses before cleaning them. The enzymes in our mouth break down organic matter.

Step 04

As they consume more than what their bodies need, they poop out the rest. Just like everything else in life.

That poop then becomes like a glue.

These glues become the foundation for soil aggregates.

Imagine bacteria create building bricks.

Step 06

And as the fungi moves through the soil, it connects those soil aggregates. These become the foundation for soil structure.

Step 07

As populations of bacteria and fungi increase, higher-level organisms come along to feed on the bacteria and fungi for their nutrients.

Step 08

Much like what we know about the above ground predator-prey food web.

Step 09

The higher-level organisms include protozoa, amoebae, nematodes, and some fungal-looking strands called actinobacteria.

Step 10

Within active and diverse soil food web, these organisms make minerals and nutrients available to plants and build soil structure able to retain moisture and oxygen.

This is known as nutrient cycling. Think of this process like the microorganisms are building soil cities.

By understanding and supporting the presence of a diverse soil food web, we support the health of regenerative soil which ensures nutrient cycling, feeds and protects our plants, increases production, flavor and nutrient density, which in turn feed our guts, fuel mental clarity, can ease inflammation, and ease the effects of compound stress and trauma.
